Practice and Revision - Ratio and Proportion
Let us practise and revise what we learned about ratio and proportion. Ratio and proportion, extending earlier concepts, involve solving mor
Core concept
Continued proportion involves three or more quantities where the ratio between consecutive terms remains constant, like a:b = b:c.
How it works
If a:b = b:c, then b is called the mean proportional, calculated as b = √(a×c).
Why it matters
Properties of proportion, like invertendo, alternendo, and componendo-dividendo, help simplify and solve complex proportion problems.
Key detail
Ratio and proportion applications extend to real-life situations like mixing solutions, scaling recipes, and financial calculations.
